Definitions
- the present invention relates to assistance with driving road vehicles. It is applicable on a road network with a specific infrastructure, such as a set of fixed beacons distributed regularly along the road.
- the device proposed by the publication FR 2.552.573 allows a central line or transmission network management unit in common, to establish from all the signals collected by tags, information usable by users.
- the present invention aims to provide vehicles moving along road axes equipped with an infrastructure of fixed beacons, transmitters and receivers, driving assistance based on the simultaneous dissemination of general information, and information dedicated to each vehicle.
- the messages are communicated to users according to the progress of their vehicle.
- each vehicle can have on request general information relating to the road network.
- the invention further provides that the vehicle is equipped with a system radio communication system connected to the computer for transmit emergency calls associated with the vehicle position on the road network, intended for emergency services competent.
- the central station 1 of the system has been shown, connected by wire or wireless, according to a network 6, to a set of fixed 4j beacons, distributed along a road axis, including a highway.
- Station 1 is also connected to several 2i information sources, such as weather stations, fuel rate indicators, service advertisers available in service and rest areas, operators showing the average vehicle speed on each section motorway, or the presence of accidents, traffic jams, etc.
- the various information received by central station 1 is processed by it and transmitted to 4j tags, from where they are broadcast towards 3p vehicles.
- FIG. 2 shows schematically that each 3p vehicle according to the invention is fitted with a badge 13 enabling it to receive over the air 5, the information sent by the beacons 4j and to transmit this information to a computer 7.
- a computer 7 This is connected for example to a memory card 8 storing data relating to the general infrastructure of the road network, to a vehicle progress sensor 9, and at an interface 10 comprising in particular a display screen 10a, a system for speech synthesis 10b and a controller 10c, such as a satellite under steering wheel.
- the computer 7 is also connected to various vehicle traffic condition sensors 11r, including fog, heavy rain, and ice detectors, an average speed calculator etc ..., and an accident sensor, sensitive to shocks.
- the computer 7 can advantageously be connected to a mobile radio communication system, such as a radio telephone 12.
- the driving assistance method proposed by the invention is the next.
- Central station 1 collects from different 2i sources information transmitted to tags 4d. 3p vehicles receive this information via their badge 13, and stores it in the memory of the computer 7. The latter also performs a cyclic reading of the progress sensor 9, to calculate the vehicle position.
- the signals supplied by the sensor 9 are moved to the position of the last tag received, so that the computer accurately determines the longitudinal position of the vehicle on the network. Furthermore, as certain parameters for calculating the longitudinal displacement of the vehicle may change over time, the computer may, if necessary, take advantage of the registration by the tag, to recalibrate these settings.
- Knowing the exact position of the vehicle allows the calculator 7 to determine to what extent it is concerned by the security information transmitted by the beacons, so systematically impose the display of relevant information on screen 10a or their voice synthesis in the passenger compartment of the vehicle by the system 10b mentioned above.
- the driver has access to the information produced by the computer 7 and by central station 1, using interface 10.
- the invention however provides that these are displayed or announced only at the request of the user, who can interrogate the computer 7 for this purpose, at using his command 10c.
- the computer 7 is connected to traffic condition sensors 11r. In accordance with the invention, it constantly scans the information given by these sensors, and can thus record all particular events detected on a section determined for example by two beacons consecutive. These events are associated with their position exact longitudinal axis, and all of these data can for example be stored in the badge 13, until the passage next to the vehicle in front of a 4j beacon, which will take care of them send over network 6 to central station 1, from which they will be broadcast to other affected vehicles.
- the invention further provides that the driver can use his control unit 10c for transmitting an emergency call, to the attention of the competent emergency services. If the vehicle is equipped with a mobile radio communication system, such as a radio telephone 12, this emergency call will be advantageously sent by the latter, either at the initiative of the driver using its control member 10c, or automatically on the order of the vehicle accident sensor. Finally, in all accident cases or breakdown, the position of the vehicle and the character of the event can be integrated automatically into the emergency message.
- a mobile radio communication system such as a radio telephone 12
- the proposed driving assistance process is therefore based on the collection and dissemination of personalized information to cars.
- the information, coming from various sources, is continuously enriched by the information sent to the station central from each vehicle while some messages are triggered according to the progress of the vehicle.
- This process therefore makes it possible to present in real time to each driver safety instructions and custom messages specific to facilitate driving, such as a list of road sections to borrow, and associated guidance information (panels).
- the road network users thus have precise information on load shedding routes that will allow them to escape traffic jams announced.
- the invention offers a solution particularly suited to the problem of systematic issuance of emergency calls, from a vehicle in distress, and from alert information of imminent danger.
